From 03ba5d5187b009e01215b3f74e508d986b912efb Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Mon, 20 Jun 2016 18:55:04 -0400 Subject: [PATCH] serial: vt8500_serial: make it explicitly non-modular The Kconfig currently controlling compilation of this code is: drivers/tty/serial/Kconfig:config SERIAL_VT8500 drivers/tty/serial/Kconfig: bool "VIA VT8500 on-chip serial port support" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. We don't replace module.h with init.h since the file already has that. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
